Really that doesn't seems Fortran specific.. so I CCed GCC list...

How you configure? Usually trunk builds fine with:

PATH_TO/configure --prefix=/usr/local/gfortran --program-suffix=-4.9 
--enable-languages=c,c++,fortran --enable-checking=release 
--enable-threads=posix --enable-libgomp --enable-bootstrap 
--with-arch=native --with-tune=native --with-fpmath=sse 
--disable-libmudflap --disable-shared

The only problem is this:

but this patch

   Re: Failure bootstrapping GCC trunk on Cygwin

seems to fix it...


Ciao,
